Abstract
A composite window structure is described for transmitting x-ray radiation and for shielding radiation generated debris. In particular, separate layers of different x-ray transmissive materials are laminated together to form a high strength, x-ray transmissive debris shield which is particularly suited for use in high energy fluences. In one embodiment, the composite window comprises alternating layers of beryllium and a thermoset polymer.
Claims20
A composite window structure for transmitting x-ray radiation and for shielding radiation generated debris, comprising:
- a layer of a first x-ray transmissive material;
- and
- a layer of second x-ray transmissive material having a thermal conductivity greater than the first material and being at least .about.12 .mu.m in thickness, wherein said layers are laminated face-to-face.
A composite window structure for transmitting x-ray radiation and shielding radiation generated debris, comprising:
- alternating layers of x-ray transmissive materials laminated together;
- wherein the materials are selected from a first group of high melting point materials and from a second group of high tensile strength materials and the materials from the first group have a layer thickness of at least .about.12 .mu.m sufficient for the first material to act as a heat sink.
A composite window structure for transmitting x-ray radiation and for shielding radiation generated debris, comprising:
- a layer of a first x-ray transmissive polymeric material;
- and
- heat sink means with the first layer for maintaining the structure strength of the first polymeric material.
